EDWARD P. WAGGONER, OF SYRAOUSE, NEW YORK.

STEAM-HEATER.

SPECIFICATION forming part of Letters Patent No. 402,635, dated May '7, 1889.

' Application filed August 10, 1888.- Serial No. 282,402. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD P. WAGG'ONER, of Syracuse, in the county of Onondaga, in the State of New York,'have invented new and useful Improvements in Steam-Heaters, of which the following, taken in connection with the -accompanying drawings, is a full, clear, and exact description.

This invention relates to an improvement in steam-heaters; and it consists in certain novel peculiarities of the construction and arrangement of the same, substantially as will be hereinafter more fully set forth, and specifically pointed out in the claims. i

In order. to enable others skilled in the art to which myinventionpertains to make and A use-the same, -Iwill now'proceed to ndescribe its constructionanduse, referring to the accompanying drawings, in which- Figure 1` is a side elevation of myimproved heater; Fig. 2, a front elevation of the same; Fig. 3, a longitudinalvertical.section of the device, taken on the line Qc a," of Fig. 4; and Fig. 4 is a horizontal section taken on a line as indicated by y y in Fig. 8.

I prefer to construct my heater of a substantially square or rectangular form in general outline, as clearlyshown in the drawf ings, the peculiar form and construction shown giving me a largely-increased heatingsurface in proportion to the amount of gratesurface necessary; and the form of my sections, it will be noted, issuch as to spread the water in the boiler into thin sheets, more effectively acted upon by the heat generated in the flre-pot. Y

Each side or section of my heater is cast or formed hollow and separate Vfrom each other section, as clearly seen in Figs. 3 and 4. The lower part of each side section is thus formed into -a thin hollow box, a, surrounding the fire-pot and forming the walls of the same; and in the lower walls of each section is also formed an opening or openings, a', these openings in the several sections being arranged to coincide when the sections arel bolted together and form feed-passages, so that when the heater is put together the dierent sections communicate and form practically lone hollow shell around the whole heater. The upper part of each side section is formed with a series of hollow projections,

`of the heater.

sults'and extract the utmost heat from the fuel. Each section is also formed with one, two, or more smoke-hues, b, which pass vertically through the hollow section and open freely through its top and through its lower outer side wall, as fully seen in Fig. 3.

Upon the top of the heater, the sides or main body of which is so formed, is secured a flat hollow top section or steam-dome, c, a space, b', being left between the dome and boiler proper to permitthe smoke and products of combustion to pass freely over the side sections and down through the flues b, and a steam-connection, c', is formed between the top section or dome, c, and each of the side sections, so that free circulation is had at all times throughout the parts of the heater.

and outside of the opening of the smoke-fines I form the raised projection or chamber a4, which is extended up to meet the top section When the heater-sections are in position, the ends of these projecting chambers abut and aid in inclosing the space o and preventing thel passage of smoke, dto., over the top of the heater-sections, causing the same to pass down the flues.

Through such of the sections a as are nec-l essary I form passages to connect with the 'usual and necessary fire-door, d, &c., and provide also an ash-pit door, d,and the other usual and necessary appurtenances of this nature.

In the bottom of the fire-pot I place the grate, consisting in this case of a series of rocking bars, d2, secured in a square or rectangular frame, e, which is `supported upon flanges e on the sides of the ash-pit, and thus when any repairs are needed I open a door, e2, provided for that purpose, and simply draw out the whole grate-frame, readily sliding it back upon its supportingiianges when completed, and by this construction considerable IOO time and expense are saved in making repairs, it not being necessary to take apart lthe heater, as is so often the case.

The heater is surrounded by an outer shell,

f, of any suitable material, provided with a smoke-escape pipe, f', and in Fig. 3 I have shown in dotted lines a dctiector, f2, by which the products of combustion, as they leave the iiues Z1, are made to circulate around the out- 1o side of the hollow fire-pot sections a before they can reach the smoke-escape pipe, thus utilizing these products to the lastdegree.

For convenience of operation I provide a magazine, g, suspended over the fire-pot and having ahood, g', with door g2 on top of the shell to admit the fuel. It will be noted that I provide a pipe, h, connecting the hood with the smoke-escape pipe f', and in this connection I place a valve, 7L', normally closed. This zo valve is provided on the outside of the connection h with alever-arm, h2, one end of which is provided with a weight, nl', and the other with a small rod, m, extended alongside of the hood in a suitable guide and adapted to 2 5 contact with the magazine-door or a projection on the same, as in Fig. I. When the magazine-door is opened, the weight at once opens the valve in the connection h, and any gas that may rise through the magazine is 3o carried off to the chimney and not allowed to escape into the room. IVhen the door is closed again, it engages and pushes back the rod m and automatically closes this valve till again used.

3 5 The various sections of the heater are firmly secured together by small bolts n., which are passed through one hollow section and screwed into a cross-bar, a', in the adjoining one, so that there are no long through-bolts exposed 4o to the act-ion of the heat. Proper packing is of course used at the points where water and steam connections are made from section to section, and the joints are thus made tight and no leakage occurs.

4 5 It will be obvious that the peculiar form of side section with the thin hollow projections gives me a greatly-increased surface, and that the passage of the products of combustion through and around these projections, then 5o down through the iiues and around the firepot before escaping, utilizes the last degree of heat produced bythe fuel and renders the heater economical. The construction, too, in flat hollow sections renders fewer patterns necessary and saves materially in the first cost of the heater.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

6o I. The herein-describedheater, having each side thereof formed of a separate section connected together and formed 011 their inner faces with integral heating-chambers projecting over the tire, substantially as and for the purpose specified. j

2. In an angular steam-heater, a hollow section forming one side of said heater, flues running through said section, openings adapted to be connected to the other sections, and projecting hollow chambers formed integral with the heater-section and extending over the fire, substantially as and for the purpose set forth.

3. In a steam-heater, the section composed of the lower box, a, and a series of projections above the box on the inner face of said heater-section and extending over the re, and a bearing-face on said heater provided with a water-passage, substantially as and for the purpose set forth.

4. In a steam-heater, the section composed of the lower box, a, a series of hollow projections above the box a and extending over the fire, and the raised chamber a4 on the top face of the heater, substantially as and for the purpose set forth.

In asteam-heater, the heater-section composed of the lower box, a, a series of integral projecting hollow chambers above the box, the raised projecting chamber on the top face of the heater-section, and the fines running through the heater and opening through the same on the inside of the said projecting chamber, substantially as and for the purpose set forth.

G. In a steam-heater, the heater-section composed of the lower box, a, a series of integral projecting chambers above the box, the raised projecting chamber on the top face of the heater-section, and the flues b, running through the heater and opening on the inside of the projection a4 and on the outside Wall of the heater, substantially as and for the purpose set forth.

7. In a steam-heater, a main body formed of iiat hollow water-sections cast independently, each section being formed on the Vsurface adjacent to the fire with a series of parallel hollow projections above the {ire-box, and also with the vertical smoke-Hue opening through the top of the section and also through its lower side wall, substantially as and for the purpose set forth. v
